1/ El artículo CORTO MEJOR y MÁS CLARO que he leído sobre la transmisión por el aire de COVID-19:

- Por qué la historia llevo a la OMS a negarla
- Cómo protegernos

Traducción automática del artículo de @crackedscience

www-mcgill-ca.translate.goog/oss/article/co…

@WHO

2/ "El 28-Mar-2020, al comienzo de la pandemia, la OMS @WHO tuiteó : “HECHO: #COVID19 NO se transmite por el aire”.

"Para los médicos y científicos biomédicos (incluyéndome a mí), esto tenía sentido. Se sabía que pocas enfermedades se transmitían por el aire."

3/ "Pero para los científicos de aerosoles, esto era a la vez desconcertante y exasperante."

"En siguientes 2 años, OMS y otras organiz. q inicialmente habían negado q el nuevo coronavirus pudiera permanecer en el aire y moverse como el humo cambiaron silenciosamente su postura"

1/ Must read from Dr. Raina MacIntyre:

Key quotes:

"As for denial of the risk in children, the majority of vaccine-preventable diseases that we vaccinate children against are mild in most children. Only a small percentage suffer serious complications"

thesaturdaypaper.com.au/opinion/topic/…

@Globalbiosec

2/ From @Globalbiosec:

"The denial of the airborne transmission was started by experts on @WHO IPC committee & allowed all countries to take the easy way out. If handwashing is all you need, onus can be shifted to “personal responsibility”...

3/ "... if ventilation needs to be fixed, that shifts responsibility to governments and private organisations."

"Denial of Omicron being serious suits exhausted community who wish life could go back to 2019. Omicron may be 1/2 as deadly as Delta, but D was 2x as deadly as 2020"

@IFLScience

Fact Check: Does COVID-19 Lose 90 Percent Infectiousness in 20 Minutes?

"We should definitely be wary of any tabloid headlines using the paper to urge us back to the office prematurely"

A good summary

@IFLScience

@Guardian

2/ Short version:

- Lab preprint very interesting for scientists, doesn't make wild real-world claims

- Taken at face value, preprint results contradict lots of real-world epi data

- Nevertheless @Guardian did just that, as if lab preprint results were the truth in real world

@Guardian

3/ @Guardian article reprinted, exaggerated more elsewhere to say that airborne transmission doesn't matter

When we know that superspreading events are airborne & major importance (nature.com/articles/d4158…). 1 event (Wuhan wet market) gave us pandemic

1H/ The new #COVIDHallofHumor

As many of your know we have started 2 ongoing threads of good and bad practices worldwide against COVID transmission

- #COVIDHallofShame:

https://twitter.com/jljcolorado/status/1478478901835968519

- #COVIDBestPractices:

@microlabdoc

2H/ The good examples are much more fun to compile, but unfortunately there seem to be many more bad examples everywhere.

So inspired by tweet by @microlabdoc, I thought it may be good (at least for our mental health) to start a #COVIDHallofHumor

Pls submit by adding that tag

@microlabdoc

3H/ UK 🇬🇧: Here we see @microlabdoc demonstrating a new method to clean the air of viruses

Cheap and easy. Only need pins, a scarf, disinfectant wipes, and work that you really want to avoid for the next 30 min!

@Teddybird

@Teddybird @krishlex @YouTube @gideonlasco @DOHgovph @ntfcovid19ph @iamguidodavid @friaronwater @WHO Yes, after yelling at us when we met with them (@WHO and its IPC committee) on 3-Apr-2020, when we already had MORE evidence of airborne transmission than they did for large droplets or fomites. + ignoring us later

This article tells some of that story:

wired.com/story/the-teen…

@Teddybird

@Teddybird @krishlex @YouTube @gideonlasco @DOHgovph @ntfcovid19ph @iamguidodavid @friaronwater @WHO But still a GREAT example that proves YOUR statement right: "You need be cautious with dogmatic statements be cause lives are lost when the science and interpretation of evidence is wrong"

It WAS a dogmatic statement, and lots of lives have been lost, bc @WHO's science was wrong

@Teddybird

@Teddybird @krishlex @YouTube @gideonlasco @DOHgovph @ntfcovid19ph @iamguidodavid @friaronwater @WHO And to this day, that statement still has an impact, as people in the medical profession that have public health power, refuse to accept the evidence FULLY: 0 evidence for droplets or surfaces, overwhelming evidence for airborne (short & long range).

@Teddybird @krishlex @YouTube @gideonlasco @DOHgovph @ntfcovid19ph @iamguidodavid @friaronwater @trishgreenhalgh @DFisman @CDCgov @Harvard Transmission in close proximity is dominated by short-range airborne transmission (aerosol inhalation) -- NOT droplets.

And most spaces worldwide (even the US) are poorly ventilated, as we can easily verify measuring CO2 (#covidCO2). So a lot of shared-room transmission

@Teddybird

@Teddybird @krishlex @YouTube @gideonlasco @DOHgovph @ntfcovid19ph @iamguidodavid @friaronwater @trishgreenhalgh @DFisman @CDCgov @Harvard For example the Norway restaurant superspreading event for omicron led to 75% of the current omicron cases in that country. So clearly shared room transmission is major.

And 10% of cases --> 80-90% of transmission. Mostly shared room airborne superspread: nature.com/articles/d4158…

@Teddybird

@Teddybird @krishlex @YouTube @gideonlasco @DOHgovph @ntfcovid19ph @iamguidodavid @friaronwater @trishgreenhalgh @DFisman @CDCgov @Harvard Some people argue that contact tracing results indicate that most transmission is in close proximity. But that's a circular argument. Contact tracing only investigates close proximity.

Like drunk person who only looks for keys below the streetlight (en.wikipedia.org/wiki/Streetlig…)
